Tried the following, but with them all the problems

ASUS USB-N13 - network otpadaet after about a few moments after connecting. Connected for a long time and is not stable.
Official driver Campiglio only under the 2.6 kernel (and duroe 2016!), ie not actually Campiglio.

TOTOLINK N300UM - absolutely similarly, falls off the network after a couple of minutes. Official driver not Campiglio.

TL-WN723N - the official firewood supplier website is also not Campiglio. Works a little better than the previous one, because from linking holds up better. But there are problems with the network connection and periodically the computer hangs tightly.

Also, I tried to take wood for rilakovic chipsets from here Campiglio, put the effect is zero.

The first two clearly Salut adapter that support Linux, the ASUS is not even the box says. That's just who the 2.6 kernel need in 2016, is not very clear.

UPDATE: Tried it here I first forgot to copy the blacklist, but when I copied it even the list of networks it sees. Apparently something failed to load.

TP-Link TL-MR3020 with the LEDE (OpenWrt) client mode. This, of course, not quite usb wi-fi adapter, but it works without problems. When connected to the usb power supply is not required, the consumption in the range of 200mA. Use this option for more than two years to connect to the network of several Raspberry Pi 24x7.

If you need to support 5GHz, MIMO, or 802.11 ac, then either Intel (M. 2 or Mini PCIe) or access point with external power supply.

PS Official driver is what is in the kernel, ath9k, for example, or iwlwifi. It's not all bad. Before you buy any equipment you need to Google.

upd 2017: appeared In the sale TP-Link TL-WR902AC - updated TL-MR3020 with support for 5GHz and 802.11 ac. Works great LEDE 17.01.2 ( ), low energy consumption. There are step-by-step instructions for setting up client mode in the bottom of the page ("Doing this via the Web GUI instead").

Wood? OpenWrt? Seriously?
TP-LINK TL-WN722N under Ubuntu - 14.04, 16.04 - undecided myself, without any issues and just works.
I love that after waking the machine from sleep mode the adapter might not Wake up. Is there a similar problem on Windows - not tested.

Possible problems with the energy - saving- I had this on rtl8192be. You can try to disable those functions. First, make a modinfo rtl8192cu and look option energy saving. Then in some of the files in /etc/modprobe.d options add rtl8192cu <опция1>=0 <опция2>=0 ... etc. and reboot. Can help.
